October: Whale Moon

The largest mammal of all – in South Africa and the world – is the blue whale, which can grow to 33 metres in length.

Of the eight whale species found in South African waters (including the dramatic black-and-white killer whale), the most frequently seen is the southern right whale. This imposing creature comes into coastal bays to calve, allowing for superb land-based viewing.

The southern right whale (Eubalaena australis) and humpback whale (Megaptera novaeangliae) are the two best known whale species that calve along the South African coast between June and December. These giant aquatic mammals were once hunted almost to extinction, an activity in which whaling stations along the South African coast were active participants. Now the numbers of these giants of the ocean are slowly recovering and they return to the warmer waters along the south and south east coasts of South Africa, where they were once butchered in large numbers, to calve in safety. Their arrival and stay has become a welcome attraction for the general public and tourists in coastal towns.

The southern right whale represents one of conservation’s success stories. Once considered the “right” whale to hunt, its population became so depleted that it was designated a protected species.

With the greater familiarity that their return to the coastal bays has produced, they are now as well loved as the many dolphins in our coastal waters.

The second Full Moon in October is the Elephant Moon.
